by installing an error context subroutine that will provide the file name
and line number for all errors detected while reading a config file.
Some of the reader routines were already doing that in an ad-hoc way for
errors detected directly in the reader, but it didn't help for problems
detected in subroutines, such as encoding violations.
Back-patch to 8.3 because 8.3 is where people will be trying to debug
configuration files.
regis. Correct the latter's oversight that a bracket-expression needs to be
terminated. Reduce the ereports to elogs, since they are now not expected to
ever be hit (thus addressing Alvaro's original complaint).
In passing, const-ify the string argument to RS_compile.
Apparently it's a bug I introduced when I refactored spell.c to use the
readline function for reading and recoding the input file. I didn't
notice that some calls to STRNCMP used the non-lowercased version of the
input line.
- ispell initialization crashed on empty dictionary file
- ispell initialization crashed on affix file with prefixes but no suffixes
- stop words file was run through pg_verify_mbstr, with database
encoding, but it's supposed to be UTF-8; similar bug for synonym files
- bunch of comments added, typos fixed, and other cleanup
Introduced consistent encoding checking/conversion of data read from tsearch
configuration files, by doing this in a single t_readline() subroutine
(replacing direct usages of fgets). Cleaned up API for readstopwords too.

Oleg Bartunov and Teodor Sigaev, but I did a lot of editorializing,
so anything that's broken is probably my fault.
Documentation is nonexistent as yet, but let's land the patch so we can
get some portability testing done.
